CHARLES MESSICK, 0F I-IACKEN SACK, NEW JERSEY.

ELECTROLIER-FITTING.

Application filed October 24 To all whom it may concern:

Be it .known that I, CHARLES MnssIoK, a citizen of the United States, residing in Hackensack, county of Bergen, State of New Jersey, have invented ,certain new and useiul Improvements in Electrolier-Fittings, of which the following is a specification.

The object of my invention is to provide a cheap'and simple fitting, and parts immediately associatedtherewith, by means of which a pull switch may be mounted in the center of an old or new multiple arm electrolier, with ease and convenience, even after the electrolier is'in place.

Reference is made to the accompanying drawing, forming a part of this spec1ficaindicate like parts.

Figure l is a view partly in section and trolier provided with my improvedfitting. Fig. 2 isa detail of the fitting, this vlew showing my improved sleeve, and the is a section, taken at right angles to Fig. 2, but showing the same parts.

The tubular electrolier arms appear at 2. A metallic shell member 3 engages the support 1 and the arms 2. This shell member is provided with a detachable portion 3 which serves the purpose of aclosure mem-' her. The shell member 3 and; its closure member 3" together constitute substantially a sphere, .as may be understood from Fig. 1. Located Within this shell is a distributing box 4 which is connected with the inner extended portions of the arms 2 and the support 1. The distributing box 4 is provided with a bridge 5 extending across its bottom, which except for this bridge is open. Below the distributing box 4 is a sleeve 6, provided externally at its lower end with a thread 6. The sleeve 6 is further provided at its top with a massive portion 6*, this portion being threaded internally. A threaded stud 7 fits into the portion 6 of the sleeve. Two nuts 7*, 7 are fittedrevolubly upon the threaded stud 7. The nut 7 may be rotated so as to jam it against the bridge 5, thus preventing relative movement between thestud 7 and the distributing box 4. The sleeve 6 is turned until it is properly adjusted relatively to the stud 7 and when this is done, the nut 7 is tightened against the upper end of the sleeve 6. The sleeve 6 is provided with a hole 8 extending through Specification of Letters Patent.

its Wall, and is also provided with a cylindrical passage 9 into which this hole merges.

A pull switch is shown at 10 and is pro- Vided with a'neclr 10 the upper edge of which is adapted to lodge against the adjacent surface of the closure member 3. closure ,member is provided with a hole through which the sleeve 6 extends. The neck l0 is threaded internally'to fit upon the lower or threaded portion. 6 of the sleeve 6. In order to render the sleeve 6 universal in its application, I make it as short as practicable. By doing this. and by varying the length of the stud 7, the sleeve and parts associated with it may be adapted for electroliers of diilerent sizes.

In practice the Wires are threaded downwardly through the tubular supporting member 1 to the distributing lqox 4, and thence through the arms 2 to the amps, and also through the hole 8 and passage 9 into the pull switch 10. p The construction above described is especially adapted for use in connection with the standard multiple-arm electrolier. Usually in such electroliers the main wires are joined, within the shell 3, to the pairs-of wires leading through the respective arms to the lamps. In such constructions the closure member 3 of the shell 3 is held in place by a standard stud having a 4-27 thread, and upon the lower end of such stud is mounted an ornamental nut, which presses upwardly against the bottom of the closure member, so as to hold it in place.

\Vith the constructions heretofore employed, when it is desired to control all of the lamps from the floor below an electro lier, a flexible cord is passed into the shell, and a pendant switch is located at the bottom to the cord. WVhen, however this pend-- ant switch is installed low'enough to be readily reached by the operator, it is apt to he in the way of tall people walking di rectly under the elcctrollcr. Again, a flexible cord is expensive, and is troublesome to install. Suppose now, it be desired to install my improved lilting and parts immediately associated therewith in place of a flexible cord and pendant switch. This-is done by merely shortening the stud, enlarging the stud hole in the shell in order to ad mit the sleeve 6, then screwing the sleeve The pull switch. is next screwed directly upon the bottom oi": the sleeve 6 as above described. in ag iplyingg This my fittings, I require only short wires to connect the switch to the electrolier, and dispense with the flexible 'cord and the pendant switch. By doing this I save time and trouble, and also attain convenience, Sim plicity and cheapness.

I claim: 7

1. As an article of manufacture, a fitting for electroliers comprising a body member having a substantially cylindrical form and provided at one of its ends with a massive portion, and with a hole extending through said massive portion in the general direction of the axis of said body member, said hole being threaded internally, said 'body member'being further provided withan axially disposed channel of greater cross diameter than said hole, said body member being also provided with'a laterally disposed opening merging into said channel, and with a thread located externally of said body member and adjacent the end thereof opposite said end bearing said massive portion.

2. In an electrolier, the combination of a central cast-ing provided with a bridge, a

stud secured to said bridge, a fitting mounted upon said stud and provided with an axially disposed channel and with a laterally disposed opening merging into said channel to enable wires to be passed through said fitting, a shell member partially inclosing said central casting, means for supporting said central casting rigidly in relation to said shell member, a second shell member detachably engaging said first mentioned shell member, and coacting therewith to completely inclose said central casting, said second mentioned shell member being adapted to be held against said first mentioned shell member by pressure, and a pull switch mounted upon said fitting and provided with a shoulder for engaging said second mentioned shell member, in order tohold the latter against said first mentioned shell member.

3. A fitting for central pull switches for electroliers comprising a body member provided adjacent one of its ends with a tapped hole suitable for a standard stud, said body member being also provided with an opening disposed near the central portion of said body member, and further provided with a channel extending downwardly from said opening, said channel having a larger. diameter than said tapped hole, said body member being also provided, adjacent its end opposite said first mentioned end, with a threaded portion to which standard pull switch may be attached.
